COLOR-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 644,733, dated March 6, i900.'

Application filed September 22, 1898. Serial No. 691,599. (No model.)

To all whom zit may concern.-

Be it known that I, SEVERIN LAZARE DE LEUIL, constructor, a citizen of the Republic of France, residing at 124 Rue de France,Vin cennes, France, have invented certain new and useful Improvements in Color-Printing Machines for printing in one or several colors on dat or relief surfaces, more especially on placards, boards, or the like, and particularly on enameled plates, of which the following is a specification.

This invention relates to a machine the object of which is to convey a color or an en'- amel of any desired tint by pressure into hollow plates, these hollows or recesses representing any characters, letters,figures, stereotypes, designs, or the like.

I have represented this apparatus in the accompanying drawings, in which@ Figure 1 shows in sectional elevation the upper part of the machine. Fig. 2 represents in side sectional elevation an upper part of the machine. Fig. 3 is ,a section on line X X of Fig. 1. Fig. lis an elevation of the mechanism for driving the piston. Fig. shows the same parts in plan. Fig. 6 shows in plan a frame serving to receive the object to be printed upon, and Fig. 7 is a plan view of a stencil-plate.

As has been above stated, the object of this machine is to deposit upon placards, plates, and the like a layer of paint, enamel, or the like in a given form by means of pressure.

. For this purpose I have constructed my Inachine, by way of example, in the following manner:

In the upper part A of a machine-frame A, supporting the whole mechanism, a plate B is provided,which is litted with a piston B', which latter receives a vertical alternating movement by the driving crank-shaft J and by a connecting-rod D with an ordinary bearing for the piston and an adjustable eccentric bearing C for the driving-shaft J. The adjustment of the stroke of the plate B, by way of displacing the eccentric bearing, is obtained by means of a small external hand- Wheel O, Fig. 2, the axis of which terminates in an endless screw O', adapted to gear with a worm-wheel O", formed on the bearing itself. The plate B is, moreover, guided laterally in guides AX, provided in the frame A.

Below the plate B the machine-frame is provided with a seat or bed a, upon which another frame is adapted to rest, which latter receives the plate or the like to be printed upon. In the center of this seat 01 bed an ejector E is arranged, which is connected to the piston of the cylinder I by means of a bellows E', provided for this purpose.

The piston I of the cylinder I, which contains the viscid printing material, is rigidly connected with an endless screw X, receiving an ascending or descending movement by the rotation of a nut V, rigid with a worm-wheel U. This screw X is normally guided by two sockets b, Fig. 1, and two guides c, fixed to the cylinder, and the cylinder, which is itself removable, is held in place by means of a hinged sleeve I2.

The sleeve-sections are pivotally connected together by a vertical pin or pivot-bolt I3, and said sections when closed together engage undera ange j" on the cylinder to thereby hold the latter in place. The sleeve-sections have ears f2, which when the sections are closed together embrace a bolt I4 on the frame A, which may receive a thumb-nut to hold the sections firmly in place.

In order to permit of the/frames and plates or the like being handled, the upper part A is made movable upon the machine-frame A. For this purpose the fixed part A of the machine-frame has a rack-bar H rigidly connected with it, which rack-bar is on its part adapted to gear with a toothed pinion h, the axis of which, being supported in the movable ,upper part A of the machine-frame, is provided upon its outside with an operating hand-wheelG, whereby the plate B can be completely displaced.

The operation of the piston for pressing out the material located in the cylinder I is obtained by means of the driving-shaft J, which is provided at the side with a grooved cam I), Figs. 1 and 4. This cam actuates an oscillating lever P', which transmits its movement to a similar lever Q by means of rods g, acting as connecting-rods.

Upon the free arm of the lever Q two pawls R R are pivotally connected, which are adapted to work on two ratchet-wheels S S. One of these pawls and ratchet-Wheels imparts to the piston, and consequently to the printing material, the ascending movement by the intermediary of the shaft U and gearwheel U, while the other similar .couple of working parts communicates to the piston and to the material the opposite or descending movement.

The stroke of the pawls R R is limited by the two levers fr t", held in position at the desi red distance by the rack-bars .'15 .r'.

The two movements of the piston are adjusted in their extent as required in order to permit of the changing of the plates, placards, or the like to be printed upon. For this purpose the band-wheel or pulley T is mounted loosely upon the driving-shaft J, these two parts being rigidly connected by a bolt or pin K, actuated by a leaf or spiral spring i, the effect being to engage the bolt with the hub of the fly-wheel.

The stopping of thc plate at the upper end of itsv stroke is effected by disengaging the bolt K from the hub, this disengagement being effected automatically by the action of a spring `n and of bevel-edged oscillating levers L.

The actuation of the driving-shaft J by the band-wheel T is effected by operating a pedal N, connected to the lever L by a rod or connecting-rod on, which as it descends compresses the spring n, causes the lever L to oscillate, which in moving awayfrom the bolt leaves the latter to the action of the spring i, which drives the same and engages it with the hub of the wheel or pulley, Figs. 1 and 3.

Fig. G represents a frame g, serving to receive the object to be printed upon. The same is fixed in the center part of the fixed machine-frame A. The distributing-plate e, with the substance to make the impression, and also the frame g, (supporting the plate g2 to be printed upon,) are seated upon springs g', which latter seat directly on seat a. The cut stencil-plate e2 is fitted into grooves e of plate e, from which the printing substance issues through the holes representing letters, numbers, and other characters or designs just far enough to be even with the outer surface. The socket E ofl plate e has a iiange E', to which is secured by screws fu a flange E2, secured to the bellows. The bellows F when the printing substance used is viscous or of rather great consistency becomes slightly dilated by taking in some of the substance forced back through the pressure exerted by the platen B, thus obviating the danger of spreading the substance over the stencil-plate e2 and of producing blurred outlines on the printed material. The lower end of the bellows F is secured between a flange F' and the ange of cylinder I, the fianges being connected together by screws t'. The bolt K, which can slide in a ring lr.' fast on shaft J, is adapted to enter the recess 7a in the hub of pulley T, said bolt being constantly impelled toward and into the hub of the pulley by spring t'. The disengagement between shaft J and pulley T is effected by releasing the foot-lever N, by which then the rod m under the tension of the springs n operates the level` L and causes this latter to engage with its ineline between the inclined head of the bolt K and the hub of the pulley, which then revolves free upon the shaft.

The operation of the apparatus is as follows: The pump barrel or cylinder I having been charged with printing substance, the stencil-plate e2 and the plate g2 to be printed upon are arranged in their proper place. By now engaging together the shaft Jand pulley T the printing substance is gradually but very slowly forced to the level with the stencilplate e2, whereupon the platen B descends immediately and presses the plate g2 for printing, together with its frame g, by compressing the springs g thereof against the stencilplate e2 and so into contact with the printing substance level with the stencil-plate. At the moment when the plate is imprinted the shaft J and its connected parts, including the cam I), have only performed half a revolution, and during the next half-revolution the platen B is caused to ascend while the piston I descends. If at the completion of the revA olution the foot-lever is set free, the springs n n actuate the lever L to disengage the bolt K from the pulley, thus stopping the mechanism and enabling the plate and, if desired, also the stencil-plate to be changed. To enable this to be effected by means of the hand wheel G, pinion h, and rack H, (the pinion 7L being on shaft h5, which is mounted in bracket 706,) the portion A' of the frame is moved rearward, and after then having changed the plate as required the portion A is replaced, and thereupon the foot-lever N is moved to engage the pulley and the operation is 'repeated.

lVhen it is desired to print simultaneously in two or more colors, I furnish my machine with the required number of additional cylinders similar to that shown in the drawings, each such cylinder containing a different color and leading by its upper end into one of the compartments formed in the distribnt ing-plate e by means of vertical partitions upon which is placed the stencil. These partitions may be fixed either to the plate e or to the stencil, as may be most convenient.
